Measuring Yb 3+ spatial distribution in horizontally grown YAG crystals

摘要

Rare Earth doped YAG crystals with controlled variable doping, are laser gain materials recently attracting much attention due to the unique properties it offer in terms of laser engineering. It is very important to perform an accurate and reliable doping spatial distribution measurement in order to be capable to fully map the doping values in the obtained material. We therefore cross-evaluated most common methods. We also mapped doping distribution in a Bagdasarov grown Yb:YAG crystal.
